ABSTRACT:
This invention is in an improvement in electrostatic spraying apparatus for coating objects with electrostatic powder, or dust. The apparatus includes a housing or body member having a discharge nozzle at one end and internal flow passages for conducting compressed gas supplied from an external source to the discharge nozzle and a deflector element coaxially disposed adjacent the discharge end of the nozzle. A source of powder or dust is provided and is mixed with the compressed gas to produce a powder gas mixture which is fed to the flow passage. Electrodes connected to a high voltage source are provided within the flow passage and at the discharge end of the nozzle to ionize the powder gas mixture. The invention provides a hollow oval shaped charging chamber within the nozzle communicating with the flow passage so that the powder gas mixture passes therethrough and is ionized therein. Auxiliary compressed gas is also passed to the nozzle and is ionized so that upon being discharged at the tip of the apparatus, it assists in augmenting the final charge of the powder which substantially improves the electrostatic application to the object being coated.
